• 关闭并尝试重新打开文件会生成一个空白选项卡。
• 尝试打开其他文件也会生成一个空白选项卡。
• 打开多个选项卡会生成 NullPointerException。
• 重新启动 Eclipse 将 Eclipse 恢复到功能状态。
• 使用 JS 编辑器(Chrome 图标)代替 JavaScript 编辑器似乎可以解决该问题(仅当尚未触发上述错误时才有效)。
  • 我担心使用 JS 编辑器会阻止我使用其他依赖 JavaScript 编辑器工作的插件。

---

我尝试了什么

• 正在卸载未签名的插件 ( AngularJS Eclipse )
• 重新安装 Eclipse Neon
• 重新安装未签名的插件(AngularJS Eclipse - 同上)

---

注意事项

为了首先启动 Eclipse Neon，从 eclipse.ini 中删除了以下行:

-vmargs

---

临时解决方案

如 howlger's answer 所示，这是由 JavaScript 编辑器未正确处理解析异常引起的问题。

这是原始文件的精简版，展示了问题:

(function() {
    var app = angular.module('TestModule', []);

    app.controller("TestController", [ '$http', function($http){

    ]});
})();

• online Esprima parser帮助我发现我在第 6 行错放了一个方括号。

修复后的代码如下:

(function() {
    var app = angular.module('TestModule', []);

    app.controller("Test Controller", [ '$http', function($http) {

    } ]);
})();

Answer 1

Eclipse Neon 包含使用 Esprima 的 JavaScript 开发工具 (JSDT) 2.0作为解析器。 (Esprima 是用 JavaScript 编写的，由 JSDT 通过 Nashorn 执行。)在您的情况下，Esprima 无法解析您的 JavaScript 文件，并且 JSDT 2.0 不是很健壮(没有回退策略)来处理此类问题。试试parse your file with Esprima online . JSDT 知道这些 Esprima 问题和 plan to replace it in an upcoming version ( Eclipse bug 497249 )，也许在 9 月的 Neon.1 中。遗憾的是，只要 JSDT 无法解析您的文件，您就无法使用 JSDT JavaScript 编辑器。
